I have used the Lorax Project in my classroom every year to wrap up several 5th grade science ideas before the test. In this unit we review advertising, Earth's resources, relationships with organisms and environments, analyze and interpret information. Key concepts covered are Natural resources, Renewable energy resources, Non renewable energy resources, Conservation of resources, Persuasion of Advertisement, and Critical Thinking. This fun and interactive unit is always a hit with my class. Covers several Texas TEKS. This is a 1 week unit.
